If the Windows 2000 / Windows XP Command Extensions are enabled the PROMPT command supports the following additional formatting characters:
$+ zero or more plus sign (+) characters depending upon the depth of the PUSHD directory stack, one character for each level pushed. $M Displays the remote name associated with the current drive letter or the empty string if current drive is not a network drive.
To enable or disable the command prompt extension in Windows 2000 or Windows XP, use the following registry hack:
Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Command Processor
Name: EnableExtensions
Type: REG_DWORD
Value: 1 enable
Value: 0 disable
You can enable/disable the extensions for the command shell you are in by issuing the following commands:
cmd /y disables command extensions for this cmd session
cmd /x enables command extensions for this cmd session
